Here's my conspiracy theories, I'm not one to believe them normally, but I'll throw these out there by saying if something weird is going on with the campaign, this is what they are likely to be, IMO:
1) Create the impression something is wrong, beyond what we have seen, attempt some kind of replacement on the ticket option "Look he's not well ok, you guys got to replace your candidate, let us replace ours", these votes shouldn't count, and when that obviously fails because a process isn't being followed by the GOP like it was the DEMs, they will use that to cry foul and that the election isn't fair and blah blah blah which will lead with chaos (their hope)
2) He knows he's losing and this is more about his trials and making him look unfit to be charged because it would be cruel.
